If you plan to market to this group read bridal magazines to keep abreast of the latest styles and trends, attend trade shows in your area, and talk to other people already working in the industry.
Don't make the mistake of disqualifying someone as a resource just because they may not specifically be in the wedding business. DJ's, photographers, florist, and caterer's can often give you valuable insight and information into the wedding industry.
Approach some of the bridal salons in your area and ask if you can leave brochures, business cards, and sample wedding favors to display. If the salon is planning a grand opening, a huge sale, or an open house offer to sponsor the event. You can set up a small table to display baskets and favors. Have a guest book available to collect names and numbers for future contact. Also, make up a beautiful wedding/honeymoon themed basket and have customers drop their name in a bowl for a chance to win the basket. For the price of some punch and cookies think of all the contacts that you can make from this one event.
By the time you have your first meeting with the couple they may have already had the engagement party if they're going to have one. If they haven't thought about having one suggest that they do so (it doesn't have to be a big affair) and offer to make a centerpiece for the table. At this time you can also make suggestions for the bridal shower and bachelor party as well.
Let me take this moment to stress how important it is to show enthusiasm. You've got to make that couple feel as though designing the baskets and favors for their wedding is the most important event that you've ever done. You've heard the old saying "Make mama happy, and everyone's happy," well; "Make the bride happy and everyone's happy." Make her feel comfortable, be sincere and you're sure to get the contract.
